FASTENING. DEVICE.

Specification of Letters Patent.

Patented Oct. 30, 1906.

Application filed December 14, 1905. Serial No. 291.762.

To all whom it muy concern.P

Be it known that I, JOSEPH M. DENNEY, a citizen of the United States,residing at Huntsville, in the county of Columbia and State ofWashington, have invented a new and useful Fastening Device, of whichthe following is a specification.

This invention relates to fastening devices, v

more particularly for uniting two bodies of leather, such as the ends ofbelts, and for like purposes, and has for itsgobject to improve theconstruction and increase the efficiency of devices of this character.

With these and other objects in view,

which will appear as the nature of the invention is better understood,the invention consists in certain novel features of construction, ashereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, andin which corresponding parts are denoted by like designating characters,is illustrated the preferred formof the embodiment of the inventioncapable of carryingthe same into practical operation, it beingunderstood that various changes in the form, proportions, and minordetails of construction may be resorted to without departing from theprinciple or sacrificing any of the advantages of thisI inventionwithinthe scope Of the appended claims. Figure 1 is a sectional view of thedevice applied. Fig. 2 is a transverse section on the line 2 2 ofFig. 1. Fig. 3 is a detached perspective view of the clamp-plate. Fig. 4is a perspective view of the base-plate and its spaced studs. Fig. 5 isa perspective view of thereinforcing-washer detached. Fig. 6 is a viewsimilar to Fig. 1, illustrating a modification in the construction. viewof.a strap coupling, representing another mannerof utilizing theimproved device. Fig. 8 is a section on the line S 8' of Fig. 7. Fig. 9is a perspective view, and Fig.

10 lis a side view, partly in section, illustrating the manner ofsupplying vthe improved device in constructing a keeper or ferrule.

The improved device comprises an oblong baseplate 10, having spacedchannels or rooves 11 12 extending longitudinally therein, and withstuds 13 14 extending from between the channels and spaced from the endsof the same and from the ends of the baseplate. The studs 13 14 areformed with parallel sides and with pyraminal terminals 15 16, as shown.The studs are designed to be Fig. 7 is a plan.

` forced through the straps or other material to be connected andrepresented at 17 18, the pyramidal ends serving as awls to puncture thematerial as they are forced therethrou h with the base-plate bearingagainst one of t e straps. clamp-plate 19, having spaced apertures toreceive the studs 13.14.

Each of the apertures in the clamp-plate 19 is square or non-circular atits inner end,

as indicated at 20, and is flared Or countersunk at its outer end, asindicated at 21, so that when the studs 13 and 1,4, are fitted throughthe clamp-plate their pyramidal ends 15 and 16Vcan be riveted'or upsetin a well-known manner.

The full strength of the stock of each of the studs is thus retained andthe full strengthV portion extended into the clamp-plate for asufficient distance to utilize the same.

The studs 13 14 are preferably square in transverse section, as thisform will puncture leather or like material with less resistance.

One of the belt or strap ends is formed with a chamfered terminal, as at23, and surrounding the stud which passes through the chamfered portionis a washer 22, the latter thus bearing upon the relatively thin beltmate-.

rial and extending the bearing-surface and increasing the strength ofthe device and likewise increasing the grip between the parts.

The end Of the clamplate 10 adjacent to the washer 22 is reduced) andadapted to be bent or clenched over the washer, as shown' in Fig. 1,vand thus still further increase the holding force of the base andwasher.

When the parts are drawn together by the Bearing against the otherstrapis a 1 riveting action, the relatively soft material of IOC InFigs. 7 and 8 another way is shownfor utilizing the improved device,where a joint is required without abrupt lateral enlargements. In thismodification the strap ends are uniformly chamfered where they overlapIIO way the ends of the straps are guarded and protected from being tornloose by any obstructions with which the straps may come in contact whenin use.

In Figs. 9 and l() is shown the way in which the device is employed forconnecting the ends of a billet-keeper or like device or Where it isdesired to unite two straps end to end and Without overlap ing.

Two or more of t e devices may be employed, arranged side by side, as inFigs. 7, 8, 9, and 10, iipreferred.

Having thus described the invention, what is claimed is-- l. In afastening device, ay base having spaced channels extendinglongitudinally thereof and bearing against `one face of the belt, studsspaced apart and extending from saidbase between said channels andadapted to extend through the belt members, and a clamp-plate bearingvupon the other face of the belt and provided with apertures forreceiving said studs whereby when said studs are riveted u on saidclamp-plate the belt members will be closely engaged and the material ofone belt member compressed into the channels of the base.

2. The combination with overlapping belt ends one of which is Jformedwith a chamf'ered terminal, of a fastening device comprising a basebearing against said chamfered portion and with spaced studs adapted toextend through both thicknesses of the belt, a clamp* platebearingagainst the unchamfered belt portion and apertured to receive said studsand a washer upon one of said studs between said base and the chamferedbelt portion and bearing over the same.

8. The combination with overlapping belt ends one of which is formedwith a chamfered terminal, of a fastening device comprising a basebearing against said chamfered portion and with spaced studs adapted toextend through both thicknesses of the belt, said base having spacedchannels extending longitudinally thereof and bearing against theadjacent face of the belt a clamp-plate bearing against the unchamferedbelt portion and apertured to receive said studs, and a washer upon oneof said studs between said base and the cliamfered belt portion andbearing o ver the same.

4. The combination with overlapping belt ends one of which is formedwith a chamfered terminal, of a fastening device comprising a basebearing against said chamfered portion and with spaced studs adapted toextend through both thicknesses of the belt, one end of said base beingreduced, a clamp-plate bearing against the unchamfered belt portion andapertured to receive said studs, and a washer upon the stud adjacent tothe reduced end of the base and bearing upon the chamfered belt ortion,and over which said reduced portion of the base is clenched.

In testimony that I claim the foregoing as my own I have hereto ailixedmy signature in the presence of two witnesses.

JOSEPH M. DENNEY.
